Dolphin Colour Vision
To able to see colors, the retina must have at least 2 different kinds of cones, with different sensitivities. Most mammals have 2 types of cones: L-cones (sensitive to long-wavelength light, red to green) and S-cones (sensitive to short-wavelength light, blue to violet or near UV). Humans and some other primates have 3 types of cones, giving them a better color vision.
Only a few land mammals. Here, we have discussed, "What colors do Dolphins see," along with the explanation of their vision. to gain the knowledge.

Can dolphins see color? It is bеliеvеd that dolphins havе vеry limited color vision. This reason is they only havе onе typе of conе cеll in thеir rеtina. It is believed that dolphins have very limited colour vision, if any at all.
For animals that can see colour a special type of cell called a cone cell can be found in the retina. Cone cells are sensitive to light occurring in different colour spectrums. Humans have three different types of cone cells which gives us good colour vision.

However, they have poor color vision with just blue and green color reception. The dolphin retina has a reflective layer called the tapetum lucidum, which bounces light back through the rods to enhance vision in dark or murky waters. It creates the distinctive eye shine seen in dolphin eyes at night.
How Well Can Dolphins See Out of Water? The spectral performance of the dolphin visual system has been investigated primarily from the behavioral and coarse psychophysical perspectives (Madsen, 1976). The Madsen (1976) color vision study boiled down to a visibility spectrum study when, after more than 15,000 trials under several different behavioral protocols, the single subject continued to respond to perceived target brightness. The common pattern in terrestrial mammals is dichromatic colour vision based on two spectral types of cone photoreceptors in the retina (commonly green and blue cones).

Behavioural studies in a few pinnipeds and one dolphin species suggest a similar type of dichro. However, dolphins lack the cones that enable colour vision, so they are likely to be colour blind. Bottlenose Dolphin spy hopping.

That is why we have a wide range of colour vision. Are dolphins and other aquatic animals color blind?
